What They Do
CheckWatt operates as an energy service company specializing in the measurement, monitoring, and control of energy storage, renewable electricity production, and flexible electricity consumption (source: checkwatt.se). The company has developed a unique "virtual power plant" technology that integrates various flexible energy resources, including residential and commercial batteries, electric vehicle chargers, solar installations, and wind turbines, to optimize grid stability and profitability (source: checkwatt.se). This innovative approach allows CheckWatt to aggregate numerous small and large batteries, enabling customers to participate in electricity markets and ancillary services that would otherwise be inaccessible due to scale limitations (source: checkwatt.se). Their flagship product, EnergyInBalance, provides a data visualization portal for customers to monitor their electricity consumption and production from various sources, enhancing user engagement and operational efficiency (source: checkwatt.se).
Projects & Track Record
CheckWatt has achieved several significant milestones in its operational history. In the winter of 2022/2023, the company successfully delivered local flexibility for the first time, utilizing a 300-kilowatt battery on the Stockholm Flex market (source: checkwatt.se). In November 2023, CheckWatt was awarded first prize in the E-Prize innovation competition for energy optimization, highlighting its commitment to advancing energy solutions (source: checkwatt.se). A major operational achievement occurred in summer 2024 when CheckWatt reached 100 megawatts of ancillary services delivery, fulfilling one-fifth of Sweden's total FCR-D ancillary service demand (source: checkwatt.se). The company also connected its 10,000th site to its virtual power plant, showcasing its rapid growth and integration capabilities (source: checkwatt.se).
Recent Developments
In April 2025, CheckWatt was acquired by Emaldo Power, creating the Nordic region's largest renewable energy aggregator (source: checkwatt.se).

Prior to this acquisition, CheckWatt reported a remarkable revenue growth of 146 percent in 2024 compared to 2023, driven by its aggregation services for approximately 15,000 customers (source: checkwatt.se).
